Not much. The pressure would drop significantly, very quickly.... you can't really use a "tank" for a bbmg, per say. You need a compressor or a CO2 setup to feed those air-hungry beasts.

Yep. I'm sure you'd get that much out of it.

5" PVC? That stuff is really hard to find.
But it fits 2 liter bottles so it's worth it.

whynot just go with like 3 peices of 3 inch for like 3 chambers made into one chamber. it would be eisier then finding 5 inch.

How powerful is your compressor? If you are going for a compact cannon, you might be better off going with a foot or so of 4" sch80 and run it at higher pressures (same amount of air, greater energy density = same bang with smaller chamber).
5" PVC? That stuff is really hard to find.
But it fits 2 liter bottles so it's worth it.

Hmm....two liter bottle chambers are nifty too have you looked at those designs?

Just save for like an 80 buck compressor.

look at how he made his bbmg portable. this is really the only effective way to go about it.
